Current version: beta, supports two-dimensional plots
i-sight is a mesh visualization and scientific plotting software
that has the ability to visualize three dimensional meshes in
perspective, axonometric or orthogonal views, and has options to
perform shading based surface visualization. In the first alpha
release, the software mainly supports mesh visualization,
the next release will contain the tools for plotting
(two-dimensional and three dimensional plots) and contour drawing.

Most other open source mesh visualization software contain
a few tools for mesh visualization and lack a complete set of tools.
For instance, most of them have ability to zoom and rotate but do
not have tools to change between perspective and orthogonal views,
perform shading based surface visualization, or the ability to
cut a mesh to see inside. The cut tool is useful for
solid meshes. In a solid mesh, wireframe model can get uninformative
for meshes with a few hundred cells. Surface model only helps in
visualizing the outer surface and not in visualizing inner cells.

Please see user documentation for a
complete list of features supported by the current release of
this software.

To compile and run this software, JDK 5 or higher is needed (available free of cost from sun microsystems.

The tool includes ability to plot, manage and modify two-dimensional plots. The two-dimensional chart area can be brought up by clicking on the toolbar button for two D charts:
The two-dimensional plotting abilities have been summarized below:

Financial charts showing daily open, close, high, low and volume.

Ability to open plots in different plot windows or in same plot window.

Draw lines on top of plots.

Line plots show the point on curve below the cursor (coordinates shown in highlighted box).
